One in 9 Australians has asthma and around half have poor control. The total cost of asthma to Australians was  approximately $28 billion in 2015. 

Australians use 20 million pressurised metered dose inhalers (pMDIs) every year. The carbon footprint of these pMDIs' hydrofluorocarbon propellant is over 600,000 tonnes CO2e – equivalent to the emissions of 350,000 vehicles or the sequestration potential of 60 million trees per year. 

This project responds to the National Health and Climate Strategy Action 4.14, to improve respiratory health outcomes and reduce greenhouse gas emissions from respiratory inhalers. This co-benefits-oriented Roadmap presents a compelling vision for the future of asthma care in Australia. Governance and resourcing are now required to progress a collaborative national implementation strategy.
